Embodiment 1

[0136] Such as figure 1 As shown, three rows of FTO thin films as conductive substances were formed on a glass plate with a thickness of 1.1 mm as a first substrate by CVD, thereby forming a first conductive layer. Subsequently, the TiO 2 Paste of particles (particle size 20nm) and terpineol (terpineol: TiO 2 The mass ratio of the particles is 70:30) coated on the first conductive layer, and baked at 450 ° C for 30 minutes to form a semiconductor-containing layer (film thickness 15 μm, short axis width 5 mm) ( figure 2 ). Silver paste Varniphite M-18 (trade name of silver paste manufactured by Nippon Black Lead Industry Co., Ltd.) was applied to the semiconductor-containing layer by screen printing, and dried at 120° C. for 30 minutes to form a third conductive layer (film Thickness 8~15μm, some bumps)( image 3 ).

[0137] Next, the first substrate provided with the semiconductor-containing layer obtained as described above was immersed in the solution for 36 hours at ...

Embodiment 2

[0147] Except for arranging six rows of cells in series, the dye-sensitized solar cell module (module C) of the present invention was manufactured in the same manner as in Example 1 ( Figure 12 ).

Embodiment 3

[0149] Except that the third conductive layer was provided only on the first substrate, the dye-sensitized solar cell module (module D) of the present invention was manufactured in the same manner as in Example 2 ( Figure 13 ).

Abstract

A dye-sensitized solar cell module comprising dye-sensitized solar cells arranged on a flat surface. Each dye-sensitized solar cell comprises a first substrate on which a first conductive layer having a photoelectric conversion layer forming part and an extension part is provided, a second substrate as the counter electrode on which a second conductive layer having a photoelectric conversion layer provided on the photoelectric conversion layer forming part on the first conductive layer is provided, a charge transfer layer contact part and an extension part, a third conductive layer provided on the extension part of the first and / or the extension part of the second conductive layer, a partition wall separating the dye-sensitized solar cell from an adjacent dye-sensitized solar cell, and a charge transfer layer. Part or whole of the partition wall contains conductive particles having conductive layers on their surfaces. The conductive layers of the conductive particles, the first conductive layer extension part of a dye-sensitized solar cell, and the second conductive layer extension part of the adjacent dye-sensitized solar cell are electrically connected in series via the third conductive layer provided on the extension part of the first conductive layer and / or the extension part of the second conductive layer.

Description

technical field [0001] The present invention relates to a solar cell module having a dye-sensitized photoelectric conversion element suitable as a solar cell. More specifically, the present invention relates to a dye-sensitized solar cell module in which a plurality of dye-sensitized solar cells having dye-sensitized photoelectric conversion elements are planarly arranged and electrically connected in series, and the dye-sensitized solar cell module has a large area and excellent performance as a solar cell. Background technique [0002] In recent years, solar cells attracting attention as clean energy have been applied to general houses, but have not been widely spread. Examples of the reasons include that the module must be enlarged because it is difficult to say that the performance of the solar cell itself is excellent; the yield of module manufacturing is low; and, as a result, the solar cell itself is expensive. [0003] Although there are several types of solar cell...
